Definitions

  • the invention relates to a connector in which terminal fittings are locked in cavities by resin locks.
  • U.S. Pat. No. 5,299,958 and FIG. 10 herein show connectors with resiliently deformable locks.
  • the connector has a housing 1 and terminal fittings 2 are inserted into cavities 3 formed in the housing 1 .
  • Each cavity 3 has a resiliently deformable lock 4 cantilevered along an insertion direction of the terminal fitting 2 .
  • the lock 4 is pushed and deformed as the terminal fitting 2 is inserted into the cavity 3 .
  • the lock 4 returns resiliently to its original shape and fits into a locking hole 5 of the terminal fitting 2 to lock the terminal fitting 2 that has been inserted to a proper position.
  • the lock 4 ideally could be thicker to reinforce the locking force on the terminal fitting 2 . However, this requires a larger deformation permitting space 6 to permit deformation of the thicker lock 4 . A larger deformation permitting space 6 conflicts with a design need for reducing the height of the connector.
  • the invention was developed in view of the above, and an object thereof is to reinforce a lock without hindering miniaturization of a connector.
  • the invention relates to a connector with a housing that has cavities for receiving terminal fittings.
  • a resiliently deformable lock is cantilevered along a wall of each cavity for locking the terminal fitting in the respective cavity.
  • a projection is formed on a surface of the lock facing the wall of the cavity along which the lock extends and a recess is formed in the wall that faces the lock for receiving the projection when the lock deforms.
  • the projection reinforces the locking force of the lock, but also reduces the amount of resilient deformation of the lock.
  • the recess in the wall of the cavity that faces the lock enables the projection to escape.
  • a necessary dimension of the deformation permitting space between the lock and the wall of the cavity is less and the connector can be smaller.
  • the cavity preferably has no side walls at the opposite widthwise sides of the lock.
  • at least one side of the lock projects from side surfaces of the terminal fitting, and the projecting ends of the lock can be pushed by a disengaging jig for deforming and disengaging the lock.
  • the locking force is reinforced by the wider lock, and the construction of a portion to disengage the lock is simplified.
  • the projection preferably is at a substantially widthwise center position and is symmetrical on the lock.
  • the lock can be deformed straight in a well-balanced manner and, as a result, the terminal fitting can be inserted smoothly.
  • the projection may be in an area of the lock excluding at least one widthwise side thereof, and only the one side of the lock contacts an opening edge of the recess when the lock is deformed.
  • the lock undergoes a twisting resilient deformation. Accordingly, a degree of the resilient deformation of the entire lock is smaller while ensuring a sufficient lifted extent of the lock to a specified position necessary for permitting passage of the terminal fitting. As a result, the deformation permitting space can be made smaller and the height of the connector housing can be reduced further.
  • a front cap preferably is mounted to the front of the housing.
  • the front cap preferably has a shake preventing wall to hold the terminal fitting tightly in cooperation with a wall of the cavity substantially opposite from the wall where the lock is provided. Thus, the terminal fitting is prevented from shaking.
  • the front cap may have a retainer to project into a deformation permitting space for the lock.
  • the front cap is mounted after the terminal fitting is inserted into the cavity and locked by the lock.
  • the retainer then projects into the deformation permitting space to prevent the deformation of the lock and hence locks the terminal fitting doubly.
  • the cavities may be provided at two or more stages, and the recess is formed in the wall to communicate with an adjacent cavity.
  • the projection preferably is formed so as not to project into the adjacent cavity also when the lock is deformed.
  • the lock preferably is substantially as wide as the cavity.
  • the projection preferably has a substantially trapezoidal cross section.
  • the projection preferably is substantially in parallel to the wall of the cavity when the lock is in an unbiased condition.
  • FIG. 1 is an exploded longitudinal sectional view of a connector according to a first embodiment of the present invention.
  • FIG. 2 is a front view of a housing main body.
  • FIG. 3 is a lateral sectional view of the housing main body.
  • FIG. 4 is a perspective view showing a portion near a locking portion.
  • FIG. 5 is a fragmentary enlarged front view showing a portion near terminal insertion openings.
  • FIG. 6 is a longitudinal sectional view showing an intermediate stage of the insertion of a female terminal fitting.
  • FIG. 7 is a fragmentary enlarged lateral sectional view showing a resiliently deformed state of the locking portion.
  • FIG. 8 is a longitudinal sectional view showing a state where the assembling of the connector is completed.
  • FIG. 9 is a fragmentary enlarged lateral sectional view showing a resiliently deformed state of a locking portion according to a second embodiment.
  • FIG. 10 is a longitudinal sectional view of a prior art connector.
  • FIGS. 1 to 8 A first preferred embodiment of the present invention is described with reference to FIGS. 1 to 8 .
  • a female connector is shown in this embodiment.
  • this female connector is roughly comprised of a connector housing 20 (hereinafter, “housing”) and one or more female terminal fittings 10 to be at least partly accommodated therein.
  • the housing 20 is comprised of two pieces, i.e. a housing main body 21 and a front wall member 40 .

  • Barrels 12 are disposed at the rear end of the female terminal fitting 10 and are configured for crimped connection with an end of a wire W.
  • a locking hole 14 having a specified length is formed over substantially the entire width in the upper surface of the connecting portion 11 and a locking section 15 projects at a widthwise center of the front edge of the locking hole 14 .
  • the connector also includes a housing 20 with a main body 21 formed e.g. of a synthetic resin.
  • the main body 21 has a tower 22 and a receptacle 23 that covers at least part of the outer peripheral surface of the front side of the tower 22 , as shown in FIGS. 2 and 3.
  • Cavities 25 are arranged at upper and lower stages inside the main body 21 and extend in forward and backward directions.
  • the female terminal fittings 10 are insertable into the corresponding cavities 25 in a rear-to-front inserting direction ID.
  • a front end of the tower 22 is divided into separate terminal accommodating portions 26 at positions substantially corresponding to the respective cavities 25 .
  • Each terminal accommodating portion 26 has a lower accommodating wall 27 that forms a bottom portion of the front surface and the opposite side surfaces of the cavity 25 .
  • the connecting portion 11 of each female terminal fitting 10 is accommodated in the lower accommodating wall 27 and fits closely along the widthwise direction (see FIG. 3 ).

  • the lock 30 is wide and the left and right sides of the lock 30 project from the left and right side surfaces of the connecting portion 11 .
  • the lock 30 extends obliquely forward in the inserting direction ID and slightly down from a base end of the terminal accommodating portion 26 .
  • the leading end of the lock 30 is resiliently deformable up in a deformation direction. As shown in FIGS. 7 and 8, the leading end surface of the lock 30 is engageable with the front edge of the locking hole 14 of the female terminal fitting 10 and the bottom portion of the locking section 15 .
  • An elongated projection 31 projects substantially at a widthwise center of the upper surface of the lock 30 and extends from the front edge of the lock 30 substantially to a longitudinal center position.
  • the elongated projection 31 has a substantially trapezoidal cross section, as shown in FIG. 7 .
  • the upper surface of the front side of the elongated projection 31 is substantially parallel to the bottom surface of the cavity 25 when the lock 30 is in an unbiased condition and the leading end surface of the elongated projection 31 defines an overhang, as shown in FIG. 1 .
  • a forwardly open escaping groove 34 is formed in the ceiling 25 A of the lower stage cavity 25 , which is the bottom of the lower accommodating wall 27 at the upper stage.
  • the escaping groove 34 communicates with the corresponding upper stage cavity 25 and is dimensioned to receive the elongated projection 31 of the corresponding lock 30 at the lower stage.

  • the opposite side edges of the lock 30 contact the side edges of the bottom surface of the escaping groove 34 to restrict the resilient deformation of the lock 30 .
  • the elongated projection 31 is set to stay in the escaping groove 34 without projecting into the cavity 25 at the upper stage at this time.
  • the connector also includes a front cap 40 formed e.g. of a synthetic resin and configured to fit on the front end of the tower 22 of the housing main body 21 .

  • the leading end of the connecting portion 11 of the female terminal fitting 10 is accommodated in the upper accommodating groove 44 and is dimensioned to fit closely therein along the widthwise direction.
  • a shake preventing wall 45 is defined at the leading end of the ceiling of each upper accommodating groove 44 and cooperates with the bottom surface of the lower accommodating wall 27 to hold the connecting portion 11 tightly.
  • each upper accommodating groove 44 at the lower stage is relatively thin and is raised up slightly from a location behind the shake preventing wall 45 to a position slightly before the rear end of the partition wall 42 .
  • This slightly raised portion of the ceiling accommodates the locking section 15 of the female terminal fitting 10 and defines a retainer 46 that enters the deformation permitting space 35 for the lower stage lock 30 .
  • a rib 47 projects on the upper surface of the retainer 46 and enters the escaping groove 34 of the lower accommodating wall 27 at the upper stage so that the upper surface of the rib 47 is substantially flush with the upper end of the escaping groove 34 .
  • the ceiling wall of the upper accommodating groove 44 at the upper stage is relatively thick and is raised up slightly from a location behind the shake preventing wall 45 to a position slightly before the rear end of the partition wall 42 .

  • Jig insertion openings 49 are formed in the surface of the front wall 41 of the front cap 40 at the left and right sides of the upper portion 28 U of each terminal insertion opening 28 , as shown in FIG. 5 .

  • the retainers 46 are retracted immediately before the corresponding deformation permitting spaces 35 for the locks 30 , and the locks 30 can deform into the deformation permitting spaces 35 .
  • the partition walls 42 enter areas before the locks 30 to form portions of the side walls of the cavities 25 .
  • the female terminal fittings 10 then are inserted from behind and along the inserting direction ID into the corresponding cavities 25 . More particularly, the female terminal fittings 10 are pushed into the cavities of the lower stage so that the locking section 15 of each female terminal fitting 10 contacts the bottom surface of the lock 30 at an intermediate stage, as shown in FIGS. 6 and 7. Thus, the lock 30 deforms into the deformation permitting space 35 and the elongated projection 31 escapes into the escaping groove 34 of the ceiling 25 A.

  • a female terminal fitting 10 might be left only partly inserted, as shown at the lower stage of FIG. 6 .
  • the lock 30 still is deformed and is in the deformation permitting space 35 .
  • the leading end of the retainer 46 will strike against the leading end surface of the lock 30 to prevent the front cap 40 from being pushed to the full locking position, thereby detecting the insufficient insertion of the female terminal fitting 10 .
  • the female terminal fitting 10 then may be pushed to the proper position and the front cap 40 may be pushed to the full locking position again.
  • the female terminal fitting 10 can be detached from the housing 20 for maintenance by first inserting a hooked leading end of a jig into the jig insertion groove 50 of the front cap 40 .
  • the hooked leading end of the jig catches the back end surface of the groove 50 .
  • the jig then is pulled forward to return the front cap 40 to the partial locking position. Accordingly, the retainers 46 are retracted before the deformation permitting spaces 35 .
  • the forked disengaging jig is inserted through the jig insertion opening 49 in the front cap 40 and slips under the operable surfaces 37 of the lock 30 .
  • the jig then is pivoted to deform the lock 30 into the deformation permitting space 35 .

  • the locking force of the lock 30 is high.
  • the elongated projection 31 on the lock 30 at the lower stage escapes into the escaping groove 34 in the lower accommodating wall 27 between the cavities 25 at the upper and lower stages. Therefore, the height of the housing is reduced while still keeping the necessary dimension of the deformation permitting space 35 between the lock 30 and the lower accommodating wall 27 .
  • Opposite sides of the lock 30 contact the bottom surface of the lower accommodating wall 27 at the opposite sides of the escaping groove 34 to prevent excessive deformation of the lock 30 .
